B12J9K0E

Through Hole Resistors

B12J9K0E is one of the common through hole resistors. It is designed to be mounted directly onto the board through holes, hence its name. This makes it easy and cost effective to install. As a through hole resistor would pass a current through the substrate, it is necessary to protect the sub-circuit from potential ESD and other potential damage. B12J9K0E through hole resistors are specifically designed to do this. They are classed as radial diffused and provide exceptional high performance and reliability.

Application Field

B12J9K0E through hole resistors are used extensively in the power supply and power delivery areas. Within computers, they are essential for the correct operation of the Ethernet communication protocol. They are also used for impedance matching, power conditioning, transient suppression, and voltage regulation. In other industries, B12J9K0E through hole resistors are used for applications such as consumer electronics, aerospace, automotive, industrial equipment, medical devices, and telecommunications.

Working Principle

B12J9K0E through hole resistors work by providing resistance to the current flowing through them. The resistor ensures that the flow of current is constrained to a specific value, allowing the dissipated energy to dissipate without danger. In effect, the resistors vacuum-form the resistance along the component. This reduces the need for series interconnected resistor arrays and improves the stability of the circuit.

The resistor package comprises two metal pieces held together by a series of small contact points. These contact points, when correctly placed, form a series resistance between the inner metal plates. The response of the resistor to a given input is its impedance, which can be measured by connecting a DC voltage to it. The current passing through the resistor is limited to the impedance set by the resistor.

The resistor also features a variety of other functions and parameters that can be altered. These include tolerance, temperature coefficients, voltage ratings, current ratings, power ratings, and capacitance ratings. Each feature impacts the resistance value, which in turn affects the output voltage and current applied to the resistor. A selector switch on the through hole resistor can be used to adjust the desired output current.

Conclusion

B12J9K0E through hole resistors are essential for the power supply and power delivery areas. They can also be used for impedance matching, power conditioning, transient suppression, and voltage regulation. Their distinct construction with two metal pieces held together by a series of small contact points, creates a series resistance which limits the current passing through the resistor. The response of the resistor to a given input is its impedance, which can be altered via the selector switch. This allows for the desired output current to be obtained.
